Forest Response to Water Availability and Disturbance in the Western United States

Creator:: Berner, Logan T.
Abstract:: Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...

Evaluating the impacts of a classroom-based citizen science project on nature connectedness, science identity, and knowledge of curricular material

Creator:: Williams, Katherine A.
Abstract:: Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

Differences in Evolutionary History and Ploidy Type Shape the Interactions of Populus tremuloides Michx. with Climate

Creator:: Greer, Burke Thomas
Abstract:: Quaking aspen (Populus tremuloides Michx) is a species with high phenotypic plasticity and a broad distribution that, in the last decade, has experienced climate stress-induced mortality called Sudden Aspen Decline (SAD). In order to help mitigate the effects of SAD in the future, we need a better understanding of aspen’s...

Physiological Responses of Loblolly Pine and Douglas-fir Seedlings from Various Provenances to Timing and Frequency of Drought Stress

Creator:: Mosel, Jamie E.
Abstract:: Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...

Wild Waters : Perspectives on Oregon’s Marine Reserves as Marine Wilderness Areas

Creator:: Johnston, Jennifer R.
Abstract:: Designation of areas as marine wilderness has been proposed as a strategy for managing the increasing threats facing the world’s oceans. Although social factors influence marine protected area success, the human dimensions of marine wilderness remain minimally explored. This thesis examines views of marine wilderness expressed by a representative sample...

Understanding Citizen Advisory Boards : A National Census of Tree Boards

Creator:: Greenleaf, Sarah (Sarah Maleno)
Abstract:: Effective management of urban forests is vital to society due to the numerous ecological, economic, and social benefits they provide. In many cities, management efforts are commonly supported by citizen advisory groups, which are often generically referred to as “tree boards” within the urban forestry context. Very little is known...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

Tree Vigor Response and Competitive Zone Density in Mature Ponderosa Pine

Creator:: Shaw, Randi C.
Abstract:: This study explored the relationship of mature ponderosa pine (Pinus ponderosa Dougl. ex Laws) tree vigor and competitive zone density following thinning and fuel reduction treatments. Competitive zone density (CZD) was defined as the total tree basal area (m²/ha) surrounding a given ponderosa pine tree within a 10m fixed radius...

Overstory Structure and Community Characteristics of Oregon Ash (Fraxinus latifolia) Forests of the Willamette Valley, Oregon

Creator:: Prive, Sean
Abstract:: As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...
